Wheat shoot N concentration was greater with banded N than with broadcast N fertilizer in 2 of 4 years under weed-free conditions and in all 4 years when competing with weeds (Fig. 2). Rao and Dao (1996) previously reported higher winter wheat leaf N content with banded than with broadcast N fertilizer. It is noteworthy that broadcast N fertilizer did not increase weed-infested wheat N concentration above that of the unfertilized control in 3 of 4 years
